Education students present research at Faculty’s Annual Postgraduate Research Conference
A total of 145 postgraduate students and 55 staff members attended the University of the Free State’s (UFS) Faculty of Education Annual Postgraduate Research Conference Social Media.

“Exploring Grade 12 learners’ substance abuse and its influence on their academic performance”, “The role of the School Management Team in addressing Homophobic Bullying in Xhariep public schools” and “Exploring the use of YouTube videos in the teaching and learning of fractions in Grade 4.” 

These were some of the interesting research titles that were presented at this year’s University of the Free State’s (UFS) Faculty of Education Annual Postgraduate Research Conference. The two-day conference, now in its fifth year, took place from 6-7 October with the theme “Changing the Educational Landscape in Africa through ongoing research”. The conference is one of the faculty’s main events supporting its postgraduate students and ensuring time for completion for each one of them. 

A total of 145 postgraduate students and 55 staff members attended the conference where the faculty’s postgraduate students get exposure to present their research in front of an academic audience.

Prof Loyiso Jita, the Dean of the Faculty of Education, delivered the keynote address and spoke at length about the graduation rates of master’s and doctoral students in the faculty. He challenged the presenters to hold themselves and each other accountable for progression in their studies and to produce high-quality research that will position them and the university in good stead nationally and internationally. 

New teaching approach   

In the study “Exploring the use of YouTube videos in the teaching and learning of fractions in Grade 4”, MB Tsoaela (PhD student), explores the teaching and learning of fractions using YouTube videos in Grade 4. In trying to answer the main research question, “How do Grade 4 educators teach fractions utilising YouTube videos?” The researcher states that: “The use of YouTube videos is a very new way of learning in the South African context. This new teaching approach has proven to be exciting for young learners in Grade 4 because it has many options like animations, colourful videos, and pictures. Even though YouTube learning is exciting and fun, its implementation has challenges such as teachers wanting to use a chalkboard. Another challenge is the current load shedding.” 

Psychosocial implications of school violence

Another PhD student, MDL Stack, investigated how to design an assessment for Higher Education that ChatGPT is unable to provide an answer that will pass without human intervention in his research paper titled “Investigating an assessment design that prevents students from using ChatGPT as the sole basis to pass assessment in Higher Education at undergraduate level”. He argued that “ChatGPT has presented significant challenges to lecturers when they set assessments at tertiary level. 

“There is enormous potential for students to attempt to use ChatGPT to write and pass assessments designed at undergraduate level,” the researcher writes. 

Another research paper looked at the psychosocial implications of school violence on teachers in Motheo District public schools in the Free State, arguing that school violence against teachers continues to be a phenomenon that is increasingly disturbing, while having serious implications on South African and global societies. Many teachers suffer social and psychological stress but not much has been done to understand learner-induced violence against teachers.

Exposure for students  

Prof Matseliso Mokhele-Makgalwa, the acting Vice-Dean Research and Postgraduate Studies, says the purpose of the conference is to give exposure to master’s and PhD students to present their work in front of an academic audience (staff and students) as well as for them to get comments and feedback from experts and fellow students on their on-going research studies. 

“The conference is about sharing the ongoing research being done by our master’s and doctoral students and/or reporting on their preliminary and final outcomes of the students who are about to graduate. By presenting their work, they disseminate key findings, build relations with other students and staff, and create inter- and multi-disciplinary networks for future collaborations,” says Mokhele-Makgalwa.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
